OS X 10.9 freeze when WiFi is turned off (POSSIBLE SOLUTION)

Hi, I just found a possible solution for this problem: my MacBook Pro freeze completely (without the spinning beach ball) after I turn off WiFi.
I have a MacBook Pro 17 inch late 2007 (MacBookPro3,1 - A1229), with a NVIDIA GeForce 8600M GT 256 MB card, running OS X 10.9.
What happened:
- I updated the OS from 10.8.4 to 10.8.5
- My Mac started freezing everytime after login, I don't remember if WiFi was on or off
- Reverted back 10.8.4, thank you Time Machine!
- Updated to OS X 10.9
- Everything was OK, but then I did some work in my home and I had to turn off the modem
- Modem was off, so I decided to turn off also the AirPort card on my MacBook Pro
- After a couple of seconds my computer completely stopped responding, trackpad and keyboard were useless, the UI froze
- After pressing the power button I managed to shutdown the Mac and then start it up again
- Now after the startup process I was stuck in loop: WiFi was still off and I had few seconds to login, wait for my account to load and turn on WiFi from the menubar icon; I failed countless times!
- In an attempt to slow down the Mac and earn some more seconds I did a PRAM reset and logged in with the Shift key pressed (after typing my password)
- I managed to turn WiFi on and looked immediatly for clues on Console logs:

(Last line is me powering the Mac on, after a forced shutdown; for some reason some lines have been lost forever: before the last one, there were some more "awacsd ... KV HTTP 0")
This is what happen to my Mac when I turn off the AirPort card; I don't know if "Google Drive" or "libdispatch client" are the problem, but quitting Google Drive solved this madness.
Hope this helps.

I'm experiencing a similar issue.
In my case, a conflicting kext (kernel extension) from a vitual machine (VirtualBox) was causing an immediate freeze after turning Wi-Fi off. After disabling the kext's scripts, I can now disable Wi-Fi safely but if I reboot then the system hangs at radom instances of boot sequence (for example while showing the apple logo, or at the login screen or a few seconds after entering the password).
I can only boot in single user mode (command-option-S) so after looking around a way to turn on WiFi from the command line, I ended up using a daemon (boot script) that turns on WiFi before anything else happens (at least as soon as the airport card is running).
In any case, I left the instructions here, just for reference.
The script should be created in /Library/LaunchDaemons
It can have any name with "plist" extension, I choosen "com.fixwifi.wifion.plist"
To create the file type: nano /Library/LaunchDaemons/com.fixwifi.wifion.plist
Enter the following text (it's a lot of text, I know, but it is better than nothing):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.fixwifi.wifion</string>
    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
        <dict>
            <key>SuccesfulExit</key>
            <false/>
        </dict>
    <key>ProgramArguments</key>
        <array>
            <string>networksetup</string>
            <string>-setairportpower</string>
            <string>en1</string>
            <string>on</string>
        </array>
    <key>StartInterval</key>
    <integer>2</integer>
</dict>
</plist>
When finished, type "ctrl-x", then "y" to save and enter. Reboot.
This script will:
- try to power on the en1 interface as soon as the script loads
- if it fails (because the interface is not running yet), will try to turn it on every two seconds
- once the interface is on (exit is succesful), then unload the script.
Note that this script assumes the airport interface is named "en1". It can also work with the word "airport" (at least in my tests).
Good luck!

Will new available wifi networks be shown when wifi is turned off?

In the interest of saving battery, I would like to keep Wifi off when I am not using it. If I turn it off would the alerts of new available networks still come up and prompt me to join one?

Thank you for a prompt response. I guess that is because if the wifi is off, it cant search for it self. Would a wifi searching web app be able to search still when the wifi is off?

Share Screen does not work well when wifi is turned on.

Hello,
I'm having a minor little problem with Share Screen among 3 machines, 2 Lion OS mac pros connected with network cable, and a 3rd mbp laptop, also LION. I use share screen a lot and I am unable to connect from my main mac pro to the 2nd mac pro (via an ethernet cable) when wifi is turned on.....actually, I can connect, but it gets stuck on the "Connecting" screen and then 10 minutes later, it connects. When I turn wifi off, then hit Share Screen, the connection and response is very fast.
After several hours playing with Sharing preferences....I think it seems like a network thing. I have checked network preferences, and re-ordered them to prioritize ethernet over wifi, powered off all devices including router, and everything else I can think of. btw, the share screen connection from my laptop to the mac pro is fine, even when wifi is turned on on the laptop.
A simple work around is to just turn wifi off, make my connection, then turn wifi back on. But I'm curious and would like to solve this issue. It started after my 10.7.4 client combo update and has been working fine for several months before that, so I'd like to figure it out. Any ideas?
Thanks for all the help on these boards.

Nevermind.
I had a failing hard drive (not the OS drive) in one of the drive bays. A couple of days after I posted this question, the drive (which has been at S.M.A.R.T. status "failing" for 6 months completely died, at which point the computer wouldn't even turn on. After removing the drive, everything with the Share Screen works fine, both over network cable and wifi.

(PS: i know we could use 3G but i want to use wifi instead)

I am having a really wierd issue as well that is probally related. I dont see 95% of the album artwork associated with my music. Also, it seems as if this has gotten worse since I started using that match feature

I'm having problems with my email account. I receive emails when I'm in a wifi zone. But if the wifi is turned off and i'm not in a zone I don't receive my emails through the cellular network. Only when I power off the phone and turn it back on, do I receive the emails through the cellualr network (again with the wifi off)

In your email settings on the phone check to make sure it is set to receive emails on cellular network. It's a feature you can turn off so your phone isn't constantly updating emails on the cell network, but if you are usually in a place with wifi and aren't concerned about going over your data allowance, you can turn it back on.

Why is iMessage taking my incoming emails and then not making them available for my PC to get? Why can I not send a text msg with photos when iMessage is turned off (but MMS is still on).

Apple is great!
Why is iMessage taking my incoming emails and then not making them available for my PC to get? Why can I not send a text msg with photos when iMessage is turned off (but MMS is still on).
I compose an iMessage with the destination as my email address and I attach 2 photos I want on my PC. I send them several times from my iPhone 5C but they never arrive. I look at my ipad later and realize that it's iMessage app is getting ( and swallowing) these emails. I then turn the ipad off. Still can't get the photos through because iphone is now getting them on it's iMessage. I turn off the iMessage feature and try to send photos from text msging. Phone tells me it can't send photos unless iMessage it turned on. What happened to regular MMS text messaging? I go and try to send photos as an email attachment and see that there is no option to attach from the stupid email program. I look up online to learn about the brave new world of apple attachments and send them.
Why is iMessage taking my incoming emails and then not making them available for my PC to get?
The email program on my iphone is not configured to remove messages from the server.
If iMessage is turned off I don't have the issue.
Why can I not send a text msg with photos when iMessage is turned off (but MMS is still on).

Did not work. I've selected iMessage to ON and left it. After a few hours I recieved a message "activation unsuccessful. Turn on iMessage to try again". This has been going on for the past 3 days.

CRM 2011: when auditing is turned off, why do existing Audit records lose "New Value"?

Not sure if this is by design (if so, would love to know why!) or if this is a bug. Let's say I have auditing turned on for Accounts. I change the phone number in the Main Phone field from 555-1111 to 555-5555, and an audit record is
created showing the Old Value (555-1111) and New Value (555-5555). Great. Now I turn off auditing. The system goes back to the audit record that had previously been created, and modifies it so that it shows the Old Value (555-1111),
and inserts an icon into the New Value field indicating auditing was turned off. The tool tip for that icon states "Auditing was stopped and restarted. The new values for the fields that changed during this period cannot be identified or recorded."
First of all (minor picky issue) auditing hasn't been turned back on yet, despite what the tool tip says (says the same thing whether or not auditing is turned back on). But the real problem is
why the existing audit record's New Value would be removed... why would that happen?!? We're talking about a historical update. It really did change, and the system knew what it changed from/to, so why would the system remove that new value
from the audit record? Logically I would expect that any changes made
while auditing is off would not be logged, and that once auditing is turned back on, Old/New values would correspond to whatever was/is in the system at the time that any new audit record is created, so there may be a disconnect between an older audit
record and a new one (old record's New Value not matching the new record's Old Value, because changes were made while auditing was off). And it's quite apparent when auditing is turned off, because an audit record is created stating "Auditing Disabled".
Any ideas if there's a logical reason why it would do this, or if this is really a bug that Microsoft needs to fix? We have a client with a business need to periodically turn off auditing while integration updates run between CRM and another system
(otherwise hundreds of thousands of unnecessary audit records would be created). But if they're going to lose audit data every time they disable auditing, the auditing is worthless.

We wouldn't ever temporarily turn auditing off on purpose... it's happening when we import managed solutions. We have vendors with managed solutions that contain system entities such as Contacts. When importing their solution, it momentarily
turns auditing off on those entities. The only evidence of this is audit records indicating "Entity Audit Stopped", and of course the loss of all the most recent "new value" on all audit records. The interesting (?) parts of this are:
1. When importing the managed solution, the recommended option to keep all existing customizations is selected. I would think this would include the audit settings on the entity, but apparently not (sort of... see #2).
2. As soon as the managed solution is imported, in addition to creating an "Entity Audit Stopped" audit record on relevant entities and wiping out new values, it apparently turns auditing back on, yet there's no record of this (in customizations, the entity
still (or once again) indicates auditing is enabled; but on records for that entity, there is no "Entity Audit Enabled" record.
So, now it's on to working with the vendors, to dig into their managed solutions and see if there's a way to prevent this!

Hi Roger
Thank you for your reply.
My original feed is: http://casa-egypt.com/feed/
However, because I modified the feed http://feeds.feedburner.com/imananddinasbroadcast and nothing changed, I redirected it to another feed and then I deleted this feed.
Is there any way to change the feed in itunes? The only feed I have now is http://feeds.feedburner.com/CasaEgyptStation
I tried to restore the feed http://feeds.feedburner.com/imananddinasbroadcast but feedburner refused.
I know that I missed things up but I still have hope in working things out.

When the sound turns off on my macbook, the miniplug stereo port emits a wildly uncontroled load leading to noise.

When the sound turns off on my macbook and my macbook pro, the miniplug stereo port emits a an enormous 'pop', i.e. wildly uncontroled load leading to noise. Goundline hum follows. I am running OS 10.6.6. I have noted previous threads noting the same problem on OS 10.4.x and 10.5.
How do I stop my mac from trying to ruin my stereo and speakers every time I connect them?

You don't say which year you have, however...
...there are known problems with the mid-2010 models (see http://support.apple.com/kb/TS4088?viewlocale=en_US&locale=en_US) as well as early and late 15" 2011 models (see https://discussions.apple.com/thread/4766577?tstart=0).
Apple has taken ownership of the problems with the 2010 model but, unfortunately, the free logic board replacement for that model has probably long expired for you - three years after date of purchase.
One the 2011 models Apple has admitted no defect. You'll just have to skim the articles to get an overview of the problems that people are having (usually showing up as screen glitches at first and then going downhill from there).
Good luck,

Img alt="text" not displayed when images are turned off in Safari

I have tried to search this, but every search has returned too many posts, so I apologize in advance.
Have I made some error or is there an issue with my Safari? For some reason my Safari does not display alt="text" when images are turned off?
This is what is supposed to happen (see http://www.w3schools.com/tags/attimgalt.asp) and it works fine in my other browsers (Opera, FF), but with Safari I get nothing - no image, no alt text, no indiciation that an image is supposed to be in that place. According to w3c, Safari is supposed to be compliant.
There is no problem with the site itself, I am designing the site and test with and without images to see how it degrades. As I said, it works properly in Opera and FF - the alt="text" text is displayed in place of the image - but not in Safari.
Is this just my Safari? How do I fix this if it is?
Is it Safari in general? If so, how do we get it fixed, because this is clearly just not correct?

It's not just you. I see the same thing in my Safari. It appears to be a Safari problem, in which case the best thing to do is submit feedback to Apple's developers via the Mac OS X feedback form. (You will not receive a response, as that page notes, but the feedback will get to the people who can use it.)

Reply asap..... It's calling about 4 hours now........... I can hear any nokia tunes anymore !!!!
HELP MEEEEEEEEEEEE
Solved!
Go to Solution.

Hmmm, I am not sure if there is another way. Since the battery is not removable for users and the 8 second -3 buzzes press don't work, I don't think there are another way to get it off.
Try connect the charger to it and do the 8 second press again, if not I think you will have to either let the battery run out untill it turns off it self or take it to a Nokia care point.

ITunes 11.0.4 is shuffling music even when shuffle is turned off

Grrrr. This is really driving me nuts.
I'm using 11.0.4 on my MacBook Pro (OSX 10.8.4).
iTunes will shuffle the music I'm playing even when shuffle is turned off. It will finish track 1 of an album (for example) and then go to 9. or 11. or 7.
What the heck is going on??

Hi Allen
Many thanks for the links, although i was aware of the sleep proxy and its uses. The problem i'm having does seem to be related to this, although the key difference between what i am (or was) experiencing is the definition of 'occasionally' as mentioned on the page you linked to.
What i was experiencing was the mac mini would go to sleep then 60 second later it would stir, as if being woken to reregister its services with the sleep proxy, then it would go back to sleep. Then around 60 seconds later it would do this again, and so on and so forth until it was fully woken in one way or another.
Now i do seem to have made progress after digging around a little further. I did figure out that it was a bonjour service/ or device that was causing the mac mini to stir And as i mentioned in my previous message this behaviour would cease if itunes was closed or home sharing was turned off. So the only thing on the network that was connected to this was my 2 apple TVs. As a test i unplugged both boxes and put the mini to sleep again. Then i waited and waited and the mini stayed soundly asleep.
I have since plugged the 2 ATVs back in, one at a time, and the mini now seems to be sleeping for around an hour before it wakes, presuming to do the sleep proxy service thingo.
i'm just running another test to prove to myself that it is actually back to a more normal state with both ATVs plugged in, so fingers crossed.
if anyone knows, does this now sound like a normal setup with the way the sleep proxy works?
i suppose i should have done this at the start, but i have 1 airport extreme, and 2 ATVs (and few ipads, iphones and the like all onthe network), if that helps.
